Remote Control 54, No. 11, 1715-1720 (1993).} \itemab Summary: A user identification protocol in an access control system uses the zero-knowledge proof principle and can be employed in inteligent identification cards with a built-in computer. A demonstration of user rights and identification algorithms based on elliptic curve properties are described. \itemrv{~} \itemcc{F.1.1 C.2.1 C.2.2} \itemut{identification protocol; access control system} \itemli{} \end
